The short version

  • Only UptimeRobot has a free tier, so it costs nothing to try first.
  • Each has a real cost: Checkmk pricing is metered per service (each individual metric or sensor monitored) rather than per host, so cost scales with monitoring depth, not just server count; UptimeRobot free plan is limited to a 5 minute check interval; sub-minute checking (60 seconds) requires the paid Solo plan and faster intervals (30 or 15 seconds) require Team or Scale
